Manga Here Subscribtions(Help)

So basically in Mangahere if there is a manga you like you can press the subscribe button.that makes it so that it will email you a notification when a new chapter comes out.My question is why doesn't it work?I click the subscribe button to many mangas and it never sends me a notification when a new chapter comes out,i tried using a different email but it still doesnt work.Im using MSN so I dont know if it doesnt work with it.Please help, i get really mad when i have to go through 20 mangas to see if theres new ones.
